traditional multi-insert is to use executemany() syntax, I'm not sure if sqlite
supports values () (), anyway.
data = [
{"id": 1, "value": "foo"},
{"id": 2, "value": "bar"}
]
stmt = table.insert().values(adate=sql.func.now())
engine.execute(stmt, data)
the func.now() is a constant and the multi-values thing doesn't support
different constant expressions in each bundle as it would mean lots of
expensive isinstance() checks, if you just put it in the first element that
will work also:
data = [
{"id": 1, "value": "foo", "adate":sql.func.now()},
{"id": 2, "value": "bar"}
]
stmt = table.insert().values(data)
print stmt
